Jian J Wang eae7b476c2 UefiCpuPkg/CpuExceptionHandlerLib: always clear descriptor data in advance
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1237

Sometimes the memory will be contaminated by random data left in last
boot (warm reset). The code should not assume the allocated memory is
always filled with zero. This patch add code to clear data structure
used for stack switch to prevent such problem from happening.
